A 8-month-old female Maltese dog was presented with a history of heart murmur. In physical examination,grade 4/6 systolic murmur heard at the left heart base. Electrocardiography showed sinus arrhythmia, right axis deviation,deep S wave and splintered QRS complex. Thoracic radiography revealed enlarged right side heart and bulging ofthe main pulmonary artery. Echocardiography showed mild hypertrophy of right ventricle, a supravalvular stenosis,marked post-stenotic dilation of the main pulmonary artery and a moderately increased pulmonary arterial velocitythrough the stenotic area (4.4 m/s, pressure gradient of 78.7 mmHg). The dog was diagnosed with supravalvularpulmonic stenosis based on the diagnostic imaging findings. Medical management using β1-blocker and ACE inhibitorwas started in this dog and this is first case report described diagnostic characteristic features of supravalvular pulmonicstenosis in korea.
